F1: Very Fair to Light. Think Michelle Williams, Cate Blanchet, or Ginnifer Goodwin. What is Nail Foundation and How Should it be Worn? We all know what foundation does for the face. Now, for the first time ever, we've developed a line of full coverage nudes that extends the exact same benefits for nails. Applying Nail Foundation allows the nails to be fully covered from any imperfections while still showing off a simple, clean and very modern effect. We wanted to create an easy way for women to feel confident about their nails. You can wear Nail Foundation alone to create a smooth, blank canvas or wear it under a favorite neutral to fill ridges or cover imperfections. Either way, Nail Foundation is the perfect foundation for a perfect manicure. What are the Benefits of Nail Foundation? We often forget to consider that our nail polish choice will either compliment or counteract our makeup style and will influence the overall effect. Choosing the right color for your skin tone minimize redness, elongates the hand, conceals imperfections, and maximizes wearability. Move over french manicure, Nail Foundation is the newly updated, professional neutral nail. The chip-resistant and high shine formula is free of harmful chemicals. There is no formaldehyde, toluene, camphor, formaldehyde resin or DBP (dibutyl phthalate) in RGB colors. All RGB products are cruelty free, and made in the USA.
